THOMAS V. BROWN, OF NEV YORK, N. Y.

lMPROVEMENi'I IN GRlNDSTONE-JOURNAL BOXES.

Specification forming part of Letters Patent No. 58,768, dated October1G, 1866.

To all lwhom it may concern:

Be it known that I, THOMAS W. BROWN, of the city, county, and State ofNew York, have made a new and useful Improvement in Grindstonc-JournalBoxes; and I do hereby declare the same to be fully described in thefollowing speeication, and represented in the accompanying drawings, ofwhich- Figure l is a top view, Fig. 2 a side elevation, Fig. 3 alongitudinal section, and Fig. et an end view, of a journal-box asprovided with my invention.

The said box, ou which my improvement rests, contains twofriction-rollers, on the periphery of which the grindstone-journal restsand revolves.

It is very important to protect both the circumfercnces and the journalsof these frictionrollers from water and sand or grit thrown oft' by thegrindstone while in use, otherwise the rollers and their journals, aswell as the journal ofthe grindstone, would soon become worn orseriously injured.

In the drawings, A is the box, in which the two friction-wheels B B arearranged in manner as represented, their journals being supported inbearings a a a. a cast or formed on the sides of the box. To this box acover, O, 1s hinged at one end, as shown at b. It extends over theperipheries ot' the wheels and down their ends, and with the sides ofthe box is formed to embrace the grindstone-journal or nearly touch it.The cover O is also formed or cast with four curved ears or caps, c o cc, extending from it over the wheel-jour nals and their bearings, andalso down partially over the ends of such journals in manner as shown inFig. 2. By so extending down upon the ends of the journals the caps c ccc operate as Scrapers to remove therefrom any sand or grit which mayaccumulate thereon and be likely to get into thejournal-bearings, andthey also protect the bearings to better advantage than were they merelycarried over them.

The cover O at its fore end has two ears or projections, d d, extendingfrom it and between the two sides of the box, and so as to go underneaththe bent arms ot' aduplex 'so as to extend over and about thewheel-journals, substantially as and for the purpose specified.

2. rlhe arrangement and application of the duplex spring-catch E withthe projections d d from the cover O, and with the sides of the box A,as specied.
